This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional PIR sensors.
Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...
A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.
Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...
